Send right field type in registration/login request information

[zepatrik]

Describe the bug

Currently we get type: "text" for every string type regardless of the format set.

{
  ...,
  "methods": {
    "password": {
      "method": "password",
      "config": {
        "action": "...",
        "method": "POST",
        "fields": {
          "csrf_token": {
            "name": "csrf_token",
            "type": "hidden",
            "required": true,
            "value": "..."
          },
          "password": { "name": "password", "type": "password", "required": true },
          "traits.email": { "name": "traits.email", "type": "text" }
        }
      }
    }
  }
}

Expected behavior

Kratos should set the corresponding HTML input type/pattern for the format set in the identity traits schema.

mapping:

{
"type": "string",
"format": "date-time", // -> type datetime-local   NOTE: no timezone!
"enum": ["foo", "bar"], // -> two radio inputs
"format": "email", // -> type email
"format": "date", // -> type date
"format": "time", // -> type time
"format": "uri", // -> type url   NOTE: url is more specific than uri
"format": "regex", // -> type text
"pattern": someRegex, // -> type from format & pattern regex
"minLength": n, // -> minlength n
"maxLength": n, // -> maxlength n
"const": value, // -> type from type & disabled true
